Wuxi Nanfang Electrical Apparatus Co., Ltd

Introduction:

3AV5-12 type 3-phase Vacuum Circuit Breaker adopts ABB and SIEMENS solid sealing insulation technology, and seals the vacuum interrupter and other parts of the primary main circuit with epoxy resin material to form a pole, which has high insulation and high mechanical strength.

 

Features:

1. It avoids the impact of the harsh operating environment on the external insulation of the primary circuit, and realizes complete maintenance-free.

2. The optimized spring operating mechanism is adopted, the structure is simplified and the performance is stable.

3. It has a wide range of applications, and can be used as the control and protection of electrical equipment such as industrial and mining enterprises, power plants, and substations, and is suitable for places with frequent operations.

 

Advantage:

1.3-phase Vacuum Circuit Breaker adopts fixed installation, mainly used for fixed switchgear, such as ring main unit, box type substation or various non-standard power supply systems.

2. The main circuit adopts solid-sealed poles, and the miniaturized operation panel saves space in the cabinet.
